a plurality thereof are grouped together to form the siding, the panels will be in the same Diane and the siding formed thereby will bedevoid of bulges or warped portions causing the siding surface to present the same appearance as would be the case were the siding not formed in sections.

Figure 14. an enlarged fragmentary sectional view through one of the similar vertical joints between adjacent ones of the panels of Fig.,l0, the section being taken at the line l4l4 on Fig. 10 and viewed in the direction of the arrows.

The drawings illustrate embodiments of the invention wherein the panels comprise base or board portions of any suitable material such as hereininclusive. the base indicatedat l5 of each of the several panels represented at 16 from which the wall siding is to be produced and which would be applied to the wall surface (not shown) of a building to be covered, is provided of rectangular form corrugated lengthwise along parallel equidistantly spaced lines to cause the base IE to present grooves l1 and opposed ribs l8 in its front and rear faces, respectively,,parallel to each other and with the upper and lower edges of the base I 5.

'I h e grooves ll extend completely through the opposite ends of the base I5 and are of a depth equal to substantially twice the thickness of the solid portions of the base i5; namely, twice the thickness of the sheet from which, by Way of example, the base i5 is formed by a pressing operation, except at one end of thebase where the ribs l8 are flattened as represented at is to causethese ends of the grooves l1 to be of substantially the same depth as the thickness of the sheet from which the base i5 is made.

In the panel construction shown the base l5 presents at the end thereof opposite that at which the ribs l8 are flattened as stated, a. flange 20 and at its upper and lower edges flanges 2| and 22, the flanges 20 and 22 and'the ribs l8, except tween adjacent panels in the area at the flattened portions 19 of the latter, being in the same plane and the flange 2| being forwardly offset from thefianges 26 and 22 a distance equal to the thickness of the sheet from which the base I is formed, the flange 22 being shown as of somewhat greater width than the flan e 20 and the flange 2B reaching from adjacent the inner edge of the flange 22 to a point midway between the longitudinal edges of the flange 2!, there being provided a notch 23 at one corner of the base 85.

In accordance with the showin wherein the finished panel presents on its outer face a pattern simulating brickwork, the entire outer surface of the base is covered by a coating 26 f adhesive such as, for example, a bitumen composition as above referred to, covered at the surfaces, thereof exposed to the weather in panel assembly, by a layer of grit represented at 25, pressed into the coating 26 and adhering there-- to over such exposed surfaces. The grit this further locally pressed into the coating 26 (the coating being hot) to become covered thereby along lines or stripes 2t simulating mortar lines delineating the brick pattern which the panel is to display, the coating 26 and with it the grit 25 at the grooves ll being preferably depressed into these grooves as shown.

It is contemplated that in covering a wall sun face a plurality of the panels shown he assembled together in matching relation to produce a continuous uniform design, the panels of alternate horizontal rows thereof being staggered relative to the panels of the rows immediately above and below them, as indicated of the upper p in Fig. lwherein the two upper panels, portions of which are broken away, are shown as meeting midway between the ends of the panel beneath them as indicated at is.

The provision of the panels of the form shownand described provide for ship-lap joints bep thereof as shown and described; the lower a 1-: 22 of the panels bein lapped by the fies 2i of'the panels immediately therebelow with a portion of the coating 26 interposed between these fies as shown in Fig. a and the en es 2d of each panel being lapped by those en of the acent horizontally aligned panels which are opposite those ends having the 2d.

As will be understood, the grouping of the panels as shown and described causes the portion of the coating Ed on the flanges 2 to be. disposed between these flanges and the flanges 28 overlapping them and thus the e 51%" l surfaces of the corrugated portions of adjacent panels at the horizontal joints are in the same plane; and; furthermore causes the exposed surfaces of the corrugated portionsof adjacent panels at the vertical joints to be in the same plane as at the horizontal joints. The spaces provided at intervals between the corrugations and the underlying flange Zil and alternating with the flattened portions' 09 of the ribs I 8 maybe sealed as for example, by filling them with any suitable cement represented at 21 in Figure 5 of the one of these spaces'shown therein, it being noted that the flat toned portions 89 of the ribs it rest directly against the flange 27. a film of the coating 26 being interposed, if desired, between the flange 26 and the flattened portions w of the ribs i8. a

The preferred way ofsecuring the panels in place in grouped 1 condition" contemplates drivin I nails throughall of the labping'parts of adjacent pahels and into the structure at the rear thereof and of which the grouped panels form a covering and also, if desired, at those of the grooves which are between the lapping parts which in sures the holding of the panels of the group flatwise at their flanges 2| and 22 and the ribs it against the structure being covered, affording to the siding structure the same even appearance (free from buckles or warpage) as would be presented by a unitary sheet as distinguished from a. panel assembly. Furthermore by virtue of the corrugated feature described, whereby air spaces are afforded between the panels and the wall structure to whichthey are applied, these air spaces beingclosed in the panel assembly as 15 shown and described, the wall covered by this siding is thermally insulated to a high degree and the panels, by reason of the strength afforded by the corrugated feature, may be made from much less material than would otherwise be necessary thereby saving in cost and weight.

The base l5 may be made of any suitable material such as, for example, dry felt. fiber board, insulation board, plywood'or plaster board. A highly desirable material from which to make the base which may or may not, as desired, have applied thereto any suitable water-proofing material, comprises two sheets of Kraft paper with a layer of bitumen composition interposed therebetween and united thereto as by means of heat and pressure; the blank from which the base is to be formed being pressed in heated condition into corrugated form in which form, upon cooling, it becomes set.

According to the embodiment of the invention shown in figures 10-14 inclusive, the panel (a grouping of a plurality of which is shown in Figure 10 to simulate a brickwork wall, the panels being represented at 28) is formed of a base 29 comprising a rectangular sheet 30 of any suitable all material such as, for example, as explained, of

the base 85 to a face of which at its margins, slats 'tl, 32, 33 and 3B of any suitable material, as for example, wood, disposed in a rectangular arrangement and rlb forming numbers 35 shown as extending parallel with each other and with the upper and lower edges of the base 25 and spaced apart. are secured, these slots and rib-forming .members being of the same thickness. The slat SI shown as extending along the lower horizontal edge of the base 29 and the slat 33 at the lefthand end of the base, extend downwardly and laterally, respectively, beyond the edges of the sheet 35 at which they are located and the slat 32 extending along the upper edge of the base 25 and theslat 36 at the righthand end of the base are set back a slight distance from the respective adjacent edgesof the sheet 30, thereby creating ship-lap-joint-forming elements which serve as means, in the staggered grouping oi a plurality of panels as shown in Figure 10, to permit the provision of ship-lap joints between each panel at its surrounding marginal edges and the panels adjacent thereto; the disp s tion of the parts of the panels as shown and described causing the panels to bear flatwise to their slats 3|36 and the. rib-forming members 35 against the wall surface to which the panel assembly is applied with their forward exposed surfaces disposed in the same plane and thus rendering the siding free from bulges or warpage and givin thereto the same appearance as in the case of siding formed of a single sheet instead qfbne iormed insections.

Furthermore, the provision of the slats 3l--36 5 and the rib-forming members 35, in combinationwith the wall to which the panel is applied, pro vides closed theme-insulation spaces between the Panel and the wall, thereby enhancing the insulating property of the structure; these slats and rib-forming members also serving as stiflening reinforcements for the sheet portion ill, of

, the panel with resultant saving in material.

As will be understood, the panel may comprise only the part which is described in both of the constructions shown as a base and which has utility'where surface ornamentation or patterning is not desired, in which case there would be interposed between the flanges 2i and 22 of adjacent panels Figures 1-9, at the horizontal joints. layers of tacky material corresponding-with the lowermost portions of the coatings 24 employed as shown in Figure 4, 'or on the other hand the panel may, as described, comprise the base and patterning or ornamenting as, for example, as disclosed; and thus in using the term panel in the appended claims it is intended that it cover both a structure in which the bare base constitutes the panel and a structure in which the base is patterned or ornamented.

While I have illustrated and described certain particular embodiments of my invention, 1 do not wish to be understood as intending to limit the invention thereto as the same may be variously modifled and altered and the invention embodied in other forms of structure without def parting from the spirit of my invention.
